On the Stationarity of Current Account Deficits in the European Union

In this paper, we test for the stationarity of EU current account deficits. Our testing strategy addresses two key concerns with regard to unit‐root panel data testing, namely (i) the identification of which panel members are stationary, and (ii) the presence of cross‐sectional dependence. For this purpose, we employ an AR‐based bootstrap approach to the Hadri (2000 ) test. While there is only mixed evidence that current account stationarity applies when examining individual countries, this does not appear to be the case when considering panels comprising both EU and non‐EU members.     

Foreign players,team production,and technical efficiency: Evidence from European soccer

As on-field success is nowadays the main objective of European soccer clubs, good management needs to extract the highest sport success from the squad talent at hand. Because teams differ in their quality, performance needs to be compared with the best practice of comparable units. One remarkable source of heterogeneity across teams is the squad composition, which can produce gains from diversity together with communication costs. The paper studies the efficiency in sporting performance of soccer teams, paying attention to how the number of foreign players relates to productive inefficiency. Using data for 146 teams in the top 5 European leagues during 10 seasons, we estimate a double heteroskedastic True Random Effects Stochastic Frontier team production function. We find that (i) the number of passes, ball recoveries, and shots from the penalty area improve team efficiency, and (ii) a higher number of foreign players increase inefficiency. Our findings suggest that gains from squad diversity might be offset by communication costs.     

数字化转型如何影响企业韧性？ ——基于双元创新视角

数字化转型是促进企业韧性形成并塑造竞争优势的重要手段。通过以广东省、江苏省等地区的339家企业为研究样本,实证研究发现:数字化转型对企业韧性具有显著正向影响;其中,数字化转型分别对探索式创新和利用式创新具有积极促进作用;同时,双元创新对企业韧性具有显著正向影响。进一步地,企业通过探索式创新和利用式创新分别在数字化转型对企业韧性的影响中起部分中介作用。研究从双元创新视角揭示了数字化转型对企业韧性的作用机制,验证了数字化转型与企业韧性的关系,也为实施数字化转型的企业通过双元创新来提升企业韧性应对不确定性风险提供了理论指导。     

要素市场扭曲与企业间生产率差异:理论及实证

资源错配突出表现为企业间持续而显著的生产率差异,这一现象在中国制造业中尤其明显.文章基于中国要素市场化改革滞后性的典型事实,研究要素市场扭曲对企业间生产率差异的影响机理.在放松了经典模型关于企业进入与退出某一行业是外生的基本假设后,新的理论分析揭示:扭曲的要素价格影响了企业的生产行为及其进入与退出决策,降低了市场均衡时生产率分布的临界值,从而使得低效率的企业得以继续存活,造成优胜劣汰的市场选择机制部分失灵,最终导致企业间生产率差异的扩大.进一步地,文章基于中国市场化指数估算了行业要素的价格扭曲程度,并利用1998-2007年中国工业企业数据库中的制造业企业数据检验要素市场扭曲与企业间生产率差异之间的关系,结果显示:要素市场扭曲指数每减少1％可以使得企业间生产率差异降低0.46％.文章对于我国当前如何矫正要素市场扭曲,并形成以市场为导向的要素价格机制,从而促进企业间的有效竞争以实现资源优化配置具有重要的政策含义.     

东北大开发中环保利益冲突及制度创新

在东北大开发过程中，加强环境保护和治理具有重要意义，而目前提出的环保政策措施，对各利益相关方之间的冲突分析不足，缺乏激励各利益团体合作的机制，以至于环保规划方案往往不能发挥它应有的指导作用。因此，要想切实促进环境保护，必须分析政府之间、政府部门之间、长期利益和短期利益之间及企业行为动机等的利益冲突，强调各方利益矛盾的协调，进行制度创新。有效的制度才能保证市场调节的正常进行，保障环保政策措施真正发挥作用。     

从我国国民经济“软着陆”看金融宏观调控的作用

国民经济的高速发展往往伴随着高通货膨胀,既保持经济的适度增长,又维持较低的通货膨胀,这是许多国家都想达到而又难以达到的理想境界。本文从我国近几年的经济发展情况出发,论述了金融宏观调控政策的内容、目标及手段,介绍了我国进行宏观调控的措施和方法,说明了金融宏观调控政策在国民经济"软着陆"中的作用。

存款保险制度的双重性及其法律对策

存款保险具有双重性，根据我国国情，建立我国存款保险制十分必要，但现实障碍也不少。应通过立法进一步深化金融改革；制定社会信用法、建立社会信用制度；健全信息沟通和披露法律制度；建立良好的监管法律机制；完善金融机构的市场退出机制；制定存款保险法律制度，依法设立存款保险机构。由此建立我国有效的存款保险法律制度，发挥存款保险制度的积极作用并克服存款保险制度的消极影响。     

Internal validity assessment of conjoint estimated attribute importance weights

This paper investigates how various conjoint designs (full versus fractional) and estimation procedures (LINMAP, MONANOVA, OLS) may interact with basic characteristics of the “true” utility functions (i.e., their range, shape, and curvature) when estimating attribute importance weights. Substantial weight distortions are found, especially under a fractional design.     

Interest rates,expectations and the credibility of the Bank of Spain

The purpose of the paper is to pinpoint the date of the change of monetary policy regime which occurred in Spain during the year 1984, when it moved away from controlling monetary aggregates towards interest rate targeting. The most likely date for the change is estimated and, surprisingly, there is evidence that agents learned about the new intermediate target quite rapidly.A week after the change, the term structure of interest rates showed how market agents attributed much more informational content to interest rate changes than they had previously. Two types of transitions are tried: a one-step and a gradual logistic swithing function.
